Granted: 1997-10-07
Abstract: The present invention discloses a process of extraction and filtration for removing iron impurities from the acid in used lead-acid batteries. Produced is a reclaimed battery acid which performs very well in new batteries and avoids costs and environmental risks entailed with present methods. In the preferred embodiment, the present invention discloses a process for rejuvenation of strip acid employed in such reclamation. In the process of removing impurities from battery acid through extraction, the extractant becomes loaded with impurities and loses its effectiveness. Extractant may be regenerated by contacting it with a strip acid. A reduction process is employed to regenerate the strip acid so that it may be used repeatedly. By recycling the extractant and the strip acid in the present invention, the present process further increases the effectiveness of battery acid regeneration--producing a reclaimed battery acid fluid which performs very well in new batteries and substantially reducing by-product waste in the regeneration of the battery acid.

Abstract: A method of identifying redundant and untestable faults in a sequential logic circuit. A lead in the circuit is selected and the circuit is analyzed to determine which faults would be hypothetically undetectable at a given time frame if the selected circuit lead were unable to assume a logic 0 at a starting time frame, and which faults would be hypothetically undetectable at the given time frame if the selected circuit lead were unable to assume a logic 1 at the starting time frame. Faults that would be undetectable at the given time frame in both hypothetical cases are identified as redundant and untestable faults. This analysis may be repeated for each of a plurality of time frames in a range of time frames which includes the starting time frame. Faults whose detection would not be possible if the selected lead were unable to assume a given value at the starting time frame may be determined based on a sequential implication procedure comprising the propagation of uncontrollability indicators and the backward propagation of unobservability indicators. An uncontrollability indicator for the given (0 or 1) value is assigned to the selected circuit lead and is propagated through the circuit and/or through a range of time frames according to a predetermined set of propagation rules. Unobservability indicators are generated in the circuit at various time frames based on the uncontrollability indicators, and these unobservabilityindicators are then propagated backward through the circuit and/or backward through the range of time frames, also in accordance with a predetermined set of propagation rules. The hypothetically undetectable faults are then defined based on the resultant indicators and their corresponding circuit leads and associated time frames.

Granted: 2000-07-25
Abstract: Four novel Bacillus thuringiensis strains, which are deposited at the BCCM-LMG under accession nos. LMG P-12592, LMG P-12593, LMG P-12594, and LMG P-13493, produce new crystal proteins during sporulation that are toxic to Lepidoptera, more particularly against Noctuidae such as Spodoptera spp. and Agrotis spp., against Pyralidae such as Ostrinia nubilalis, against Gelechiidae such as Phthorimaea operculella, and against Yponomeutidae such as Plutella xylostella, and that are encoded by a novel gene. The crystal proteins contain protoxins, which can yield a toxin as trypsin-digestion product. A plant, the genome of which is transformed with a DNA sequence that comes from either one of the strains and that encodes its respective toxin, is resistant to Lepidoptera. Each strain, itself, or its crystrals, crystal proteins, protoxin or toxin can be used as the active ingredient in an insecticidal composition for combatting Lepidoptera.
